六氢吡啶基二硫代甲酸钠盐、氯化亚铁及四硫代钼酸铵在二甲基甲酰胺及二氯甲烷中,经一步自兜反应,分别得到了[MoFe3S4(C5H10NCSS)5]DMF及[MoFe3S4(C5H10NCSS)5]CH2Cl2.通过X射线衍射测定了后者的晶体结构,比较了它与[MoFe3S4(Et2NCSS)5]^-结构特点的异同,同时研究了反应物摩尔比对产物的影响以及溶剂分子的置换反应.

MoFe3S4 singel cubane-like cluster compounds, [MoFe3S4(RCS2)5].DMF and [MoFe3S4(RCS2)5].CH2Cl2 (I) (R = piperidino) were obtained by 1-step spontaneous self-assembly reaction of FeCl2, (NH4)2MoS4 with RCS2Na in DMF or CH2Cl2, resp. I is orthorhombic, space group Pbca, with a 19.222(7), b 27.853(4), c 19.456(3) ? d.(calcd.) = 1.645 g cm3, Z = 8, R = 0.097. Its structural feature, as compared with [MoFe3S4(Et2NCS2)5], exhibits obvious differences resulting from the disparity of the core oxidation states. The effect of reactant ratio on the product and the substitution reaction of solvent mol. in these compounds were also discussed.
